Taxonomic notes
Description
S. pectinata can grow up to 75 centimeters tall, covered with stiff nonglandular hairs and is stiffly branched with the longest branches occurring at the base. Seed capsules are ovoid covered with glandular hairs and flowers are around 1 centimeter long and yellow with hairs (Musselman and Mann 1978).
Distribution
S. pectinata is much more restricted in its distribution than S. cassioides however has a broader host range. It often prefers drier sites than S. cassioides and on occasion can be found growing together. There is no evidence of hybridization between the two species (Musselman and Mann 1978).
Ecology
Habitat
In the Coastal Plain in Florida and Georgia, S. pectinata can occur in open woodlands, flat longleaf pine-wiregrass communities, sand live oak groves, and sandridges (FSU Herbarium). It also occurs along roads. Soils include sandy soil and loamy sand (FSU Herbarium).

Pollination
Deyrup conducted a study and observed these bees, Augochlorella aurata, Augochloropsis sumptuosa, Dialictus placidensis, Anthidiellum notatum rufimaculatum, A. perplexum, Coelioxys sayi, Megachile brevis pseudobrevis, M. mendica, M. petulans, and Bombus impatiens, on S. pectinata (2002).
The following Hymenoptera families and species were observed visiting flowers of Seymeria pectinata at Archbold Biological Station (Deyrup 2015):
Halictidae: Augochlorella aurata, Augochloropsis sumptuosa, Lasioglossum placidensis
Megachilidae: Anthidiellum notatum rufomaculatum, Anthidiellum perplexum, Coelioxys sayi, Megachile brevis pseudobrevis, M. mendica, M. petulans
